I think the 54cm Orca would be too big. One mitigating factor of the Diva is that the steeper seat tube angle will have the result of her needing to place her saddle further back to get the same seat position relative to the bottom bracket than a bike with a slacker STA (e.g., Orca).
One effect of having a 'smaller' bike is that there is more saddle to bar drop than with a bigger one. You can stack a bunch of spacers under the bars, but too many looks ugly.
For the kind of money you're going to spend, you really need to have your GF ride some bikes & get fit first. That would be my advice; try the Diva and have her try a Madone WSD in a 54cm (53cm TT).
Also, don't forget looks ARE important. We like to ride purty bikes & your and her definition of purty may be different.
